1Description: This Crazy zone v2 heatbreak is used for crazy hot-end printing carbon fiber, because ordinary crazy heatbreak uses 0.1mm thin-walled tube, although the performance is perfect. But when printing carbon fiber for a long time, the carbon fiber will cause the heatbreak to break, so it will be a very troublesome thing for the hot end. Therefore, we customized this super wear-resistant heatbreak made of aerospace materials according to customer requirements, which will perfectly solve the problem of customers using crazy printing carbon fiber filaments. Because of the special material, we could not keep the design of the v1 version, we carried out the design of the V2 version. To use this version of heatbreak, you need to replace a black cooling bracket. Currently, the black cooling brackets are used for Crazy, Crazy Plus and Crazy Pro. Please choose according to your hot end.We will add a black heatsink to you according to your choice.
